Prices shown in currencies other than USA Dollars are estimates based on current exchange rates. We will charge your credit card in USA Dollars on the day your order is shipped, and the conversion to your local currency will be done at the prevailing rate by your credit card issuer.

Shipments outside the USA are declared as “bike parts” for customs purposes and will include the actual amount paid for merchandise and shipping. Jenson USA will not mark your parcel as a “gift”, declare a value lower than the actual price paid, or otherwise prepare false customs information.

Shimano Ultegra FC6650 Crankset Oe No BB

Shimano’s Ultegra 6650 crankset shares its lineage with the legendary Dura Ace crankset and is designed for cyclists that are looking for a high performance crankset that won’t wipe out their savings. Featuring Hollowtech II technology, the Ultegra 6650 crankset uses outboard bearings that create a stiffer bottom bracket/crank interface and distribute load more evenly than square taper setups. SG-X technology on the outer chain ring uses teeth with special tooth profiles to ensure consistent and smooth shifting, even under load while a compact design imporves climbing performance.
